The mechanization of moulding and coremaking is the core that Foundry Production simplifies.It directly reflects the level of production of foundry.The technical process of moulding and coremaking and machinery thereof depend on the character of molding sand or core sand, the process of moulding and coremaking, and equipment etc. used, for widely used clay-bonded sand, normal employing " flask molding ", the technical process of moulding comprises the operation such as transport of filling, consolidation, molding, lower core, mould assembling and sand mold and sandbox.The type of mo(u)lding equipment is different, and its method of operating is also different, but the most basic operation all comprises filling, consolidation and molding, wherein important with consolidation.
In recent years, mo(u)lding equipment has a great development, the jolt squeezing machine generally used in the past, by Slight Shock Squeeze is replaced, there have been developed multiple contact high pressure shockless jolt molding machine, without case and drawing shoot squeeze molding machine.The particularly air impulse molding machine of development in recent years, makes moulding mechanization enter the new stage of high-quality, efficient and low consumption.
Existing air impulse molding machine is generally divided into consolidation molding sand She Sha mechanism, impeller ramming mechanism and consolidation molding sand She Sha mechanism etc., wherein consolidation molding sand She Sha mechanism comprises consolidation cylinder, capping is rotatably connected in consolidation cylinder, consolidation cylinder circumference is distributed with sand-spraying hole, consolidation cylinder is externally connected with the venting cavity of parcel sand-spraying hole, the side of consolidation cylinder is provided with air accumulator, air accumulator and venting cavity pass through pipeline communication, pipeline is provided with valve, be provided with the core box be communicated with consolidation cylinder below consolidation cylinder, the consolidation cylinder of consolidation cylinder and core box connectivity part has steam vent, its course of work is: first add molding sand to consolidation cylinder, rotate capping, the import of consolidation cylinder is opened by capping, molding sand will flow in consolidation cylinder, rotate capping again the import of consolidation cylinder is closed, then valve is opened, to enter in venting cavity by pipeline with the gas of certain pressure in air accumulator, enter in consolidation cylinder through venting cavity through sand-spraying hole, forming gas sand flow in consolidation cylinder injects in core box, air in die cavity in core box is discharged by steam vent, similar to the consolidation principle of ramming, the kinetic energy penetrating sand consolidation mainly sand air-flow becomes the consolidation merit of molding sand, main flow direction impacts molding sand, on non-mainstream, by steam vent inside and outside differential pressure, form the effect of filter stream consolidation.
But in the process of consolidation, the switch of capping and the switch of valve need to control respectively, when needing to open capping, just necessary first valve-off, when needing to open valve, just first must close capping, operating procedure is more, reduces operating efficiency.
Summary of the invention
The invention is intended to provide a kind of consolidation molding sand She Sha mechanism increased work efficiency.
Consolidation molding sand She Sha mechanism in this programme, comprise consolidation cylinder, consolidation cylinder circumference is distributed with sand-spraying hole, consolidation cylinder is externally connected with the venting cavity of parcel sand-spraying hole, the side of consolidation cylinder is provided with air accumulator, air accumulator and venting cavity pass through pipeline communication, the core box be communicated with consolidation cylinder is provided with below consolidation cylinder, the consolidation cylinder of consolidation cylinder and core box connectivity part has steam vent, slidably connect capping in consolidation cylinder, capping is engaged with gear, and gears meshing has tooth bar, pipeline is provided with connected chamber, and tooth bar basal sliding is connected in connected chamber.
The know-why of this programme and beneficial effect are: first add molding sand to consolidation cylinder, slip capping, the import of consolidation cylinder is opened by capping, molding sand will flow in consolidation cylinder, capping simultaneously also driven gear is rotated, gear driven tooth bar moves, tooth bar slides in connected chamber, on pipeline, the outlet of air accumulator is closed, when molding sand reaches a certain amount of, to slide again capping, the import of consolidation cylinder is closed by capping, while consolidation cylinder is closed in capping, on pipeline, the outlet of air accumulator is opened again, to enter in venting cavity by pipeline with the gas of certain pressure in air accumulator, enter in consolidation cylinder through venting cavity through sand-spraying hole, forming gas sand flow in consolidation cylinder injects in core box, air in die cavity in core box is discharged by steam vent, similar to the consolidation principle of ramming, the kinetic energy penetrating sand consolidation mainly sand air-flow becomes the consolidation merit of molding sand, main flow direction impacts molding sand, on non-mainstream, by steam vent inside and outside differential pressure, form the effect of filter stream consolidation.
Compared with prior art, the slip that this device only need control capping just can complete, and capping is opened or closed, and the opening or closing of outlet of air accumulator on interlock pipeline, decrease operating procedure, improve operating efficiency.
Further, tooth bar slidably connects the first chute, when tooth bar slides, the first chute serves the effect supporting tooth bar, and what tooth bar was slided is more stable.
Further, capping slidably connects the second chute, when capping is slided, the second chute serves the effect supporting capping, and what capping was slided is more stable.
Further, capping is connected with cylinder, starts cylinder, cylinder drives capping to slide, and lidding tape moving gear rotates, and gear driven tooth bar moves, and facilitates opening or closing of capping, also facilitates tooth bar and controls opening or closing of the outlet of air accumulator on pipeline.
Further, be provided with the workbench supporting core box below core box, workbench can support core box, in the process of penetrating sand, ensures that core box is stablized.
